Cleaning; Inspection And Maintenance; Dhw Cylinder; Safety Valve (Dhw Cylinder) - Viessmann VITOCAL 060-A Operating Instructions For The System User

Cleaning

The appliance surfaces can be cleaned with a com-
mercially available domestic cleaning agent (non-
scouring).
No splashes of water must enter the DHW heat pump.

Inspection and maintenance

The inspection and maintenance of a heating system
is prescribed by the Energy Saving Ordinance [EnEV -
Germany] and the DIN 4755, DVGW-TRGI 2008 and
DIN 1988-8 standards.

DHW cylinder

Standards DIN 1988-8 and EN 806 specify that main-
tenance or cleaning should be carried out no later than
2 years after commissioning and as required there-
after.
Only a qualified contractor may clean the inside of the
DHW cylinder, including the water connections.
If any water treatment equipment (e.g. a sluice or
injection system) is installed in the cold water supply of
the DHW cylinder, ensure this is refilled in good time.
For this, observe the manufacturer's instructions.

Safety valve (DHW cylinder)

The function of the safety valve must be checked
every six months by the user or a contractor through
venting (see valve manufacturer's instructions). The
valve seat may become contaminated.
Water may drip from the safety valve during a heat-up
process. The outlet is open to the atmosphere.

Potable water filter (if installed)

To maintain high hygienic standards, proceed as fol-
lows:
Replace filter element on non-back flushing filters
■
every six months (visual inspection every
two months).
■ On back flushing filters, back flush every
two months.

Damaged cables / lines

If there is damage to the connecting cables or lines of
the appliance or externally installed accessories, these
must be replaced with special cables or lines. Only use
Viessmann cables / lines as replacement. For this,
notify your qualified contractor.
Regular maintenance ensures trouble-free, energy effi-
cient, environmentally responsible and safe heating.
Your heating system must be serviced by an author-
ised contractor at least every 2 years. For this, it is
best to arrange an inspection and maintenance con-
tract with your local heating contractor.
We recommend an annual function check of the pro-
tective magnesium anode by your contractor.
The function of the protective magnesium anode can
be checked without interrupting operation. The con-
tractor will check the earth current with an anode
tester.
